She can't hide her delight! Kristen Bell glows on set of Veronica Mars after celebrating gay marriage rulings

Kristen Bell was positively glowing on Wednesday on the Los Angeles set of her film Veronica Mars.

The 32-year-old actress was perhaps basking in love either from asking Dax Shepard to marry her on Twitter or from playing her favourite character.

The actress and 38-year-old Dax got engaged in 2009 and have a three-month-old daughter Lincoln, but they vowed to hold off on getting married until gay marriage was legal in their home state of California.

Kristen followed through on Wednesday after the U.S. Supreme Court ruled on two gay marriage cases when she tweeted: '@daxshepard1 will you marry me? Xo #marriageequality #loveislove'

The high court in one of the cases ruled against against California's Proposition 8 that banned same-sex marriage and opened the door for gay marriage in California.
